Referring to Figures 1, 2, 3 and 4, the numeral 30 designates a casingin the top plate 3| of which is disposed a panel 32 hinged at 33.Housings or classifying sections 34 and 35, Figures 2,

Figure 1 is an exterior plan view of a preferred 3 and 4, secured inlight-tight relationship to the panel 32, are provided with removablelighttight covers 36 and 31. The entire assembly of panel 32 andhousings 34 and 35 is adapted to be swung upward on the hinge 33, andthe front ends of the housings close upon the top plate 3| inlight-tight relationship, their bottoms 38, Figure 4, forming in effectextensions of the panel 32. When the panel and housing assembly is inclosed position as shown in the drawings, clamps 38, Figures 1 and 3,are used to maintain the parts firmly together.

The housings 34 and 35 are divided internally into a number of chambersand as these chambers are identical in both housings, they have beengiven the same identifying numerals to simplify the description.Referring to Figures 2 and 3, it will be seen that a longitudinal wall48, extending from the rear of each housing to a cross partition 4i,provides two narrow longitudinal chambers 42 and 43.

A second cross partition 44 is situated forwardly of partition 4i anddefines therewith a third chamber 45. A small light-tight box 48 isdisposed in the lower rear corner of the chamber 45 overlying a slot 41in the bottom 38. A wide slot or window 48 in the bottom 38 opens intothe chamber 45. A fourth chamber 48 comprised between the partition 44and the frontwall 58 of the casing, overlies a third slot 5I inthebottom 38.

A series of small apertures 52, 52a, 52b, 52c, 52d, 52c and 52] and asemnd series 53, 53a, 53b, 53c and 53d longitudinally spaced therefrom,are provided in the bottom 38 under the chamber 42. A plate 54, Figure2, secured in the main casing 38 below the plate 32 and casing bottom38, has a plurality of apertures 55 and 58 underlying and in registrywith those of series 52 and 53. A third series of apertures 51 in thebottom 38, registen ing with corresponding apertures 58 in the plate 54,are normally covered by cross slides 59.

The slides 59 are guided in light-tight relationship in the partitions48 and the outer walls of the casings 34 and 35. The slides are providedwith apertures 88, 88a, etc., which normally underlie the partition 48,but when in selecting position as shown in casing 34, Figure 3, theslides are drawn outward to bring the slide apertures into registry withcorresponding apertures of the series 51 as shown in detail in Figure10. Upturned tips 6| on the slides 55 are provided for drawing thelatter outward, and the surface of the plate 32 is depressed slightly at62 to receive the ends of the slides, the edge 53 of the sunken portion62 serving as a stop to assure accurate registry of the apertures. Theslides are designated beginning at the left by successive digit numerals1, 2, 3, 4, 5, 6, 'l, 8, 9, 0 and letters A, B, and C as shown at 8Ia.Similar numerals and letters Gib are imprinted upside down on the bottom38 in chamber 43 in such positions as to be normally covered by theirrespectiveslides but adapted to be uncovered when the slides are drawnforward, as illustrated in Figures 3 and 10.

A source of radiant energy 84, which may be,

her 43 and is provided with a reflecting hood 13 adapted to direct theradiant energy down-ward on the numerals and letters 8"). The source I2is also provided with a flexible external supply cable I4.

Situated under the plate 54 is an elongated light-tight chamber I5containing a photo-cell I8 underlying the apertures 58. A secondphotocell preferably of the multiple-cathode type, is disposed directlyunder the apertures 55. 55 in plate 54. This multiple photo-cell, thestructure of which in itself is not part of the present invention, maybe of the general type fully disclosed in Patent No. 2,140,799, datedDecember 20, 1938, to A. A. Kucher, and is illustrated diagrammaticallyin Figures 2 and 11. Thecell 11 includes a single anode I8 and aplurality of cathodes I9 separated by light-tight and insulating walls88, each cathode being located directly below one of the apertures 52 or56: It is obvious that if desired the apparatus may be constructed witha separate complete photo-cell for each aperture 52 and 56, but themultiple cell is preferred for compactness.

A master control record or strip 8 I, hereinafter described in detail inconnection with Figures 9 and 10, is slidably disposed between thebottom 38 and the underlying plate 54. The strip 8| is wound on suitablereels 82 and 83 rotatably mounted in. the cabinet 38 as shown in Figures2, 4 and 4a. By rotation of the reels the strip 8I may be drawn rapidlybetween apertures 41, 52, 53 and 51 in the bottom 38 and thecorresponding apertures in the lower plate 54,

A motor 84 drives a cross shaft 85, Figures 2, 4

and 4a through worm gearing 88. The reels 82 and 83 are adapted to bedriven from the shaft 85 through bevel gear trains 81 and 88 andmagnetic clutches 88 and 38 respectively. The hubs BI and 32 of reels 82and 83 to which the ends of the strips are secured in any suitablemanner, Figure 12, are made of metal and are electrically connected to asupplyconductor, 83 preferably for example, an elongated filament lampprovided with a support 65, is disposed in each chamber '42 overlyingthe apertures 52, 53 and 51. The lamp 64 is provided with a socket 68 inthe rear wall of the housing 34 and 35. Flexible supply conductors 61lead from the sockets 85 and enter the casing 38 through bushings 58.

A lens system 69 is adjustably mounted in the partition 4| betweenthechambers 43 and 48. An inclined mirror I8, Figures 2 and 3, is adaptedto reflect an image of any uncovered numerals and letters Blb throughthe lens 89 against a second inclined mirror II in thechamber 45. Theinclined mirror 1|, which is also slightly tipped laterally, directs theimage downward into the slot 48. A second source of radiant energy I2,preferably of the mercury flash type hereinafter described, is disposedin the top of the chamure 4a, which may be insulated from the cabinet 38and from the motor 84. The strip 8I'is of insulating material such aspaper, and spring fingers or brushes and 91 press against the portionsthereof rolled on the hubs 8| and 82 so that when the strip is unrolledsufliciently from either hub to allow the corresponding spring flnger toengage the surface of the hub, an electrical contact may be established.

Referring to the electrical diagram, Figure 12, it will be seen thatconductors 98 and 8!] connect the brushes 38 and 91 to the magnets I88and IN 0! a two-way toggle switch I82, the arm I83 of the switch I82being adapted to establish en- 88 from which a connection is madethrough con-' ductor 93. The second fixed contact I 88 is connectedthrough a lead II4 to one side of normally closed relay contacts Ilia,the other side of the breaker being connected through a lead Hi to thesecond magnetic clutch 88. From clutch 88 a connection is made throughwires III and I I8 to the first supply conductor 83. A normally 'openmanual switch II8, hereinafter referred to as the starter switch, isconnected across the breaker contacts Ilia by means of wires H9 and 120.

A swinging arm I2I, operable by depression of the starter switch II8,has thereon a springpressed pawl I22 adapted to actuate a small ratchetwheel I23. A holding pawl I24, also engages the ratchet wheel I23, andwhen the wheel is revolved the oscillations of the holding pawl I24 areadapted to cause a series of contacts between a pair of switch pointsI25 and I 26 situated behind the pawland insulated therefrom.

The connections and purpose of the switch points I 25 and I26 ,willhereinafter be described in connection with Figure 11a. A secondmanually operable switch I21, the purpose of which will also behereinafter explained, is also adapted upon closure to actuate the armI2I through a sliding rod I28.

The magnet of the relay H5 is connected by wires 430 and 43I with theleads 39 and H respectively, being thus arranged in parallel with themagnet IOI of the toggle switch I 02.

The operation of the master strip moving apparatus set forth above is asfollows:

The motor 84 being in operation, the shaft 85 is rotated continuouslythrough the worm gearing 86. The forward or operating movementof the.strip 8| is to the left in Figures 4 and 12 in which the apparatus isviewed from the front of the machine, this direction of movment ofcourse being to the right in the rear view, Figure 4a.

Referring to Figure 12, the parts are illustrated in starting position,that is with the strip 8I unrolled from the'reel 83 so that the brush 91is in contact with the metallic hub 82., Current passes from the'supplyconductor 93 through the hub 92 andlead 99 to the toggle switch magnetIOI, thence back to the second supply conductor I08.

The magnet IOI is energized throwing the arm I03 to the left as shownand bringing the contact member I04 into engagement with the contactI06. Thereby a connection would normally be completed from the supplyconductor 83 through leads H3 and III, clutch 90, lead II6, breaker II5,lead II4 contacts I06 and I04, and flexible lead I01 to thesupplyconductor I08. However, as the relay magnet H is connected inparallel with magnet IN, the former is also energized, thus holding thecontacts I I5a open.

The above described connection is therefore not completed and the clutch90 is not energized so that the reel 88 remains at rest. To start thecycle, the manual switch I I8 is closed, thus completing the abovecircuit around the contacts I I5a through leads 9' and I20. Theclutch 90engages and revolves the reel 83, winding the strip 8| on reel 83 andoft the'reel 9|, the strip being thus drawn between the bottom 38 andsub-plate 54, Figure 2. The first layer of the strip 8| which envelopesthe hub 92 breaks the electrical contact between the hub and the brush91. The magnet III and also the relay magnet I I 5 are therebytie-energized, allowing the contacts H511 to close. Thus, when themanual starting switch I I 8 isreleased, the c losed contacts Iliamaintain the above described clutch circuit, the strip 8| beingcontinuously unreeled from reel 82 until the end of the final layerthereon passes under the brush 96. As the brush 36 encounters the baremetal of the hub 8i it completes a circuit from the supply conductor 33through the hub 9|, brush 36.

lead 98, toggle switch magnet I00 and lead I08 back to conductor I08.The magnet I00 is energized, throwing the toggle switch lever I03 to theright and moving the contact member I04-out of engagement with contactI06. This action breaks the described circuit through clutch 90,disengaging the latter, and immediately thereafter completes a circuitfrom the supply conductor 93 through lead II2, magnetic clutch 83, leadIII, contacts I05 and I 04, and flexible lead I01 back to conductor I08.The clutch 88 engages and rewinds the strip 8| on thereel 82 until thelatters unwinding from reel 88 permits the brush 81 to again engage themetal hub 82, whereupon the electrical contact thereby establishedoperates in the manner previously described to restore the apparatus tostart position as shown, the opening of relay contacts II5a causing thereels to remain at rest until the, next operation of the starting switchII8.

From the foregoing it will be noted that a single depression of thestarting switch II8 causes the master strip 8| to be moved completelythrough.

the machine in the forward or working direction and automaticallyrewound to starting position. The gearing 81 connecting the reel 82 tothe shaft 06 may be of higher driving ratio than gearing 88 of reel 83,causing rewinding to occur at higher speed than the forward or workingmotion, thereby saving time on the rewind.

Referring to Figure 4, the numerals I28 and I30 designate film magazinesindividually removable from the casing 30. The magazine beingidenticalin structure throughout, one is shown in section and the other inexterior view. The magazines are secured in place as follows:

The top plate 3| of the casing has formed therein'transverse slots I3I,Figures 1, 3 and 4, having enlarged eyes I32'at their right ends, andsurmounted by plates I33, the latter being of tapered thickness to formwedges with their greatest thickness at the left as shown in Figure 4.The magazines I23 and I30 have transverse slides I34 equipped with knobsI35. The knobs I35 have'enlarged flanges I36 adapted to pass upwardlythrough the eyes I32 and to overliethe edges of the slots I3I when theknobs are moved to the left into locking position on the wedge platesI33 as shown in the figures. Spring pressed film guides I31 are providedin the upper faces of the magazines, and the slides I34 have inclinededges I3'Ia adapted to engage and force the guides -I31 downward whenslid to the right. 5

Thus, when the slides are in the position shown in detail, Figure 13,they constitute closures to protect the film I38 against light when themagazines are removed from the machine. The longitudinal locating meansfor the magazines com .prise angle strips I39 adapted to engage offsetsI 40 on the magazine casings, and resilient memberg I4I adapted to urgethe offsets I40 into the angle. strips. It will be observed that inorder for the magazines to be either removed from or inserted into themachine, the knobs I33 must be in extreme right hand position to permitflanges I36 to pass through the eyes I32. In this right hand position ofthe knobs the slides I34 are closed, so that it is impossible to exposethe film accidentally in removing a magazine.

In putting a magazine in place the offset I40 is inserted in the angleI39 and the magazine rocked upward, flexing the member HI and allowingthe knob I35 to pass upward through the 4r assasee the-wedge surface ofplate iiiii and clamping the magazine firmly in position.

Disposed in each magazine are two reels I42 and I43 upon which is woundthe recording medium or fllm I38. It will be understood, however, thatwhile for the sake of brevity the recording medium I38 ishereinafterreferred to as the film,-the latter word is not used in the narrow senseof photographic film, as any other suitable recording material such assensitized paper strips may be used.

Between reels I42 and I43 the film I38 passes over a metallic rollerI44, over the spring-pressed guide I31, and over a feed roller I45,Figure 4. A resilient metallic brush I46 presses the fllm against thefirst roller I44, while a hinged pressure roller I41 holds it firmlyagainst the feed roller I45.

The feed roller I45 has an outer surface preferably faced with rubber orother suitable friction material. The outer surface is interrupted atone point in its length to accommodate a ratchet wheel I48, as shown inFigure 5. A small step relay I49, having two windings I56 and Il, has apawl I52 engaging the ratchet wheel I48 and is adapted to advance theratchet one tooth for each electrical impulse directed through eitherwinding. All electrical connections for the relay I49 are carried out ofthe magazine as shown in Figure 2 by means of spring pressed pincontacts I53 disposed in an insulating panel I54 secured in the casing36.

A shaft I55, journalled in a support I56, Fig ure 2, carries on itsforward end a friction disk I 51. urged forward by a light spring I68.The shaft I55 is driven through bevel gears I59 from a cross shaft I69which in turn is driven throu h a small belt I6I from the main crossshaft 85. When the magazine is in place the disk I5! is lightly engagedby a second disk I62 on the end of the shaft of the lower film reel I43.Thus in operation, the revolving disk I51 slipping on the second diskI62 imparts a rotary urge to the lower reel I43 which is insuflicient toovercome the friction of the spring member I46, Figure 4, but whichserves to keep the film taut. This forward urge also assists the forwardfeed of the him and acts as a take-up when the step relay I49 isoperated.

It will be noted in Figure 2 that the right hand half of the film I38underlies the master strip 8| directly below the bottom slot 41 of thelighttight box 46, while the left half of the film is directly exposedto the slot 48 in the bottom of chamber 45. A source of instantaneousillumination such as a mercury flash lamp I 63 is disposed in the box46.

Computation units I64 an'd I65 (Figs. 1 and 2) are secured in thefrontportion of the casing.

36 in line with the housings 36 and 31 respectively. As these units I64and I65 are identical in structure and function, the structure andoperation of unit I64 will be described as typical of both.

Referring to the enlarged longitudinal section, Figure 6, numeral I66designates a clutch casing secured to the left end of the main body I61of the computation unit I64. A vertical shaft I68, journalled in theclutch casing I66, is adapted to be continuously driven through bevelgearing I69 from a crossshaft I19, the shaft I16 in turn being driven bya'suitable motor I1I, Figures 1, 2, 3 and 11a. It is obvious that ifdesired an individual motor may be provided for each computation unit.

, itotatabiy mounted on the shaft I68 is a. sleeve memberl12'longitudinally located between two collars I13 and I14. Two bevelgears I15 and .l16 rotatably fitted on the sleeve I12 are provided withdog teeth I11 and I18 adapted to be meshed with similar teeth on theends of a clutch or dog ring I19 slidably keyedto the sleeve I12. Thering, I19 is provided with a shifter yoke I86. The yoke carries pivots,one of which is shown in dotted lines at I88a. When in operation anelectro-magnet I8I, acting through an armature I82 and link I83,normally holds the yoke I86 and clutch ring I19 downward so that thegear I16 is clutched to the sleeve I12. When the -magnet I8I isde-energized a tension spring I83a snaps the yoke I upward drawing theclutchring I19 out of mesh with teeth I18 and into mesh with teeth I11on the upper gear I15, thus releasing the lower gear I16 and clutchingupper gear I18 to the sleeve I12.

Theupper collar I13, which is fixedly secured to the shaft I68, hasformed thereon a ratchet wheel I84, shown in plan view in Figure 8. Thesleeve I12 has on its upper end a circular flange I85 closely underlyingthe ratchet wheel I84, and a resilientfriction ring I86 is disposedbetween the sleeve I12 and collar I13 in suitable recesses. Thusrotation of the collar I13 acts through the ring I86 to exert acontinuous frictional rotative urge on the sleeve I12 and flange Adetent I81, Figure 8, pivotally mounted on the flange I86, is adapted toengage the ratchet I84 and is urged toward engagement therewith by a.spring I88. The detent I81 has thereon an outwardly extending tail I88a.Five magnetic latches I89, I90, I9I, I92 and I93, arrangedcircumferentially with respect to the flange I85, have armatures I94,I94a, I94b, i940 and I94d respectively adapted normally to engage thetail I81a. When the tail I81a is engaged by any armature, for instanceas by armature I94 of latch I89 as shown in Figure 8, the forward, motion or the flange I85 move the detent I81 out of engagement with theratchet I84 and against a stop I95. The frictional urge of the ring I86,

previously described, is sufficient to overcome the torsion of springI88, so that the detent I81 and flange I85 are held stationary in theposition shown in Figure 8. If the magnetic latch I89 is energized, thedetent I81 15 released thereby and snapped into engagement with theratchet I84, causing the flange I85 to be rotated in the direction ofthe arrow, Figure 8, until the tail I81a encounters the armature I94a oflatch I96, which again releases the detent and stops rotation of theflange I85. Similarly, energization of magnetic latch I98 permits theflange to further rotate until the tail "1:: engages the next latcharmature i941), and so on throughout the revolution.

The mechanism just described thus constitutes an intermittent or stepclutch, hereinafter generally referred to as the master clutch I96.

The position of the parts showri in Figure 8, that is with the detentI81 held bythe latch I89, is the zero or starting position of the masterclutch cycle. The magnetic latches are so arranged circumferentiallythat the angular distance in the forward or clockwise direction fromlatch I89 to latch I98 is one-eleventh of a circle, from I98.to I9I istwo-elevenths, from I9I to I92 is two-elevenths, from I92 to I93 isfiveelevenths, and from I93 to I89 is one-eleventh. Thus, it the latchesare energized successively,

it is evident that the master clutch sleeve I12, and with it whichevergear I15 or I19 is locked thereto by the dog ring I19 will be driventhrough a complete revolution in successive angular steps having therelation of 1, 2, 2, 5, and 1. Referring to Figure 6, the bevel gearsI15 an I19 are in mesh at diametrically opposite points with a thirdbevel gear I91 secured to a rear,- wardly extending shaft I99. Thenumber of teeth of either gear I15 or I19 with'respect to the number ofteeth. of the third gear I91 is in the relation of .eleven to ten.therefore, that when the master clutch revolves throughout one completerevolution, the shaft I99 is rotated throughout one and one-tenthrevolution.

The shaft I99 has secured thereon a plurality of resilient frictionaldrivers I99 arranged in caoperative pairs, each pair embracing betweenthem a spur gear wheel 299 rotatable on the shaft I99. Thus if thewheels 299 are unrestrained when shaft I99 is rotated they are'alsorotated by the friction members I99, but when the gear wheels arerestrained from rotation the friction members slip and allow the shafttoturn in the gears.

Each gear 299 is in mesh at one-to-one ratio with a similarly toothedaccumulator wheel, there being in the present example six accumulatororders designated from left to right in Figure 6 by numerals 29I, 292,293, 294, 295 and 299. These accumulator orders are'secured to nestedshafts 291 to 2I2 inclusive respectively and these shafts carry on theiropposite ends numerical drums 2I3 to 2; inclusive, the inner shaft 291being supported on ball bearings 2I9.

As all the accumulator orders and related apparatus are identical inform, the structure and operation relating to the order 29I is hereindescribed as typical. The outer rim 229 of order 29I has therein 10digital positioning notches 22I, 22Ia, 22Ib, etc. as shown in Figure 7.

A magnetic selector latch 222 having two independent releasing magnets223 and 224, is provided with a detent 225 adapted to engage the notches22I, 22Ia, etc. and thereby restrain the accumulator member or order 29Iand its gear 299 from rotation.

A normally open contactor 229 is adapted to v be closed by a cam lobe221 on the accumulator order 29I, the lobe being so located as to closethe contactor 229, hereinafter referred to as the carry-over contactor,as the accumulator member MI is moved between the nine (9) and zeropositions in either direction. A second con tactor 229, hereinafterreferred to as the positive contactor is so located as to be closed bythe same lobe 221 when the accumulator member is in nine position asshown in Figure '7, while a third contactor 229 is similarly arranged tobe closed by the lobe 221 when the accumulator member is in zeroposition, the third contactor 229 being hereinafter referred to as thenegative oontacton' Disposed on a plate 249 in the top of the casingabove the latch magnets 223 and 224 are a double-pole relay 341 and adouble-throw relay 242, the details and connections of these relaysbeing fully shown on the wiring diagram, Figure 11, and hereinafterdescribed.

A rocker shaft 243, Figures 6, 7 and 70., extends throughout the lengthof casings I99 and I91, and has thereon an armature lever 244 adapted tobe rocked, as illustrated in Figure 7a, by an elec- It is evident,

The rocker shaft 243 carries levers 249 extending adjacent the faces ofthe gears 299 and terminating in flat hooks 241'. The gears 299 havesecured therein pins 248 extending outwardly toward the levers 249. Thelocation of the pins 249 is such that they normall revolve free of thehooks 241. When the shaft 243 is rocked by the magnet 245, howe ver, thehooks 241 are lowered into position to intercept the pins 249 as shownin dotted and dashed lines in Figure 7a, the gears 299 and theiraccumulator members being thereby stopped and held as they reach zeropositions in the forward direction indicated by arrows in Figure '7. Itis evident, therefore, that if the magnet 245 be energized while theshaft I99 is revolved one revolution in the forward direction, allaccumulator orders will be cleared.

Figure 6a is a plan-view of one of the numerical drums 2I5, shown astypical of the exterior aspect of all drums 2I3 to 2I9. For each digitalposition of drum 2I5 and its accumulator order 293 a pair of digits isprinted on the periphcry of the drums, the sum of each pair of digitsbeing equal to nine. In other words, each drum carries successive digitsfrom zero to nine inclusive in the forward or positive direction withthe nines complement on each digit printed closely behind the digit onthe circumference.

Due to the use of the nested shafts, 291 to 212, it is evident that thedenominational order of the drums is reversed with respect to that ofthe corresponding accumulator orders, for example, the lowestdenominational order 299, located at the right of the accumulatorseries, controls the drum 2I9 at the left end of the group of drums. Tobring the figures on the drums in proper relationship, therefore, thedigits are printed upside down as the parts are viewed in Figures 6 and6a.

Referring to Figures 2 and 9, it will be seen that the drums 2I3 to 2I9are located directly below the bottom opening of window 5I in thechamber 49 so that a complete set of digits and their nines complementsare exposed through the opening. A thin vertical partition 249 spans thewindow 5I so as to divide the row of exposed digits from their row ofnines complementary digits. Three angular mirrors 259, 25I and 25 2 anda lens 253, the latter disposed in the partition 44, are adapted toproject an image of the exposed portions of the numerical drums on tothe film I39 as shown in dotted and dashed lines, Figure 2. Two smallhooded sources of illumination 254, and255, Figures 2 and 4, preferablymercury flash lamps or the like, are located on the walls of the chamber49 on opposite sides of the partition 249.

It is evident that if either lamp is actuated it will illuminate onlythe row of digit numerals on its side of thepartition and consequentlythe image of only that row is projected on the film I39.

Referring to the wiring diagrams, Figures 11a and 11, it will be seenthat a manual stpp switch 259 is providedjn the main supp y conductorI98 (which is connected to a source of A. C. supply), and a shortconductor 251 leads through a normally closed magnetic breaker 259 totwo branch supply line 259 and 299. Two double pole manual switches'29land 292 are adapted respectively to close connections between the mainsupply conductor 93 (which is also connected to the A. C. supply) andtwo branch supply lines 293 and 294. It will be understood that whilethe supply lines 294 and 299 furnish current as hereinafter tromagnet2&5 disposed in the clutch casing I99.

described to the apparatus associated with section 34, Figures 1 and 3,the two similar conduc- .with the latter.

branch 251 and the supply conductor, so that this motor is always inoperation when the manual stop switch 256 is closed.

The magnetic breaker 258, Figure 11a, has control leads 261 and 251aconnected respectively to a the supply line 93 and to the conductor l II, Figure 12, being thus connected in parallel with the magnetic clutch89 and operable concurrently By this means, when the clutch B9 isengaged and the master strip is being rewound to starting position, thebreaker 258 is held ,open, cutting off the current supply to branches259 and 250 to disable the classifying and com- I puting mechanism toavoid false entries in the latter.

A transformer 263, Figure 110, has its primary 255 connected across thebranch supply line 250 and 255. A heater winding 210 of the transformeris connected to the filamentoi a rectifier tube 21l. A'high voltagewinding 212 has one end thereof connected to the plates of the rectifiertube 2' and the other end grounded at 213. The transformer and rectifierjust described are for the purposeof furnishing P wer to the mercuryflash lamp I53, Figure 11. This lamp is described in a book entitled"Flash," by Edgerton and Kilian and published by Hale, Cushman and Flintof Boston, Massachusetts. The cathode 215 of the lamp I53 is connectedthrough the contacts 321b, a normally deenergized four-pole rea lay 321and a. wire 215 to the ground 213, Figure 11a.

The anode 218 or the lamp I53 is connected through the contacts 321a anda conductor 210 to a resistor 213, Figure 11a, and thence to thefilament or the rectifier tube 2. A condenser 323 bridges the anode andcathode of the lamp.

A high voltage induction coil- 25I has one end of its primary 202connected to the ground at 213; and the other end of the primary isconnected to the contact point 3I0a of a relay IIB, so that when thiscontact point is closed, it is connected to'the anode of the flash tubeI53 and to the filament o! the rectifier tube 21I (which is the sourceof high voltage) through resistor 213.

The secondary 285 of the induction coil 20I has one terminal thereofconnected via a wire 205 and the contact 3210, of relay 321 to a.conductor or plate 251 positioned closely adjacent the envelope o! themercury flash lamp I53 in the vicinity oi. the latters anode and pool ofmercury. The other end of the secondary 205 is connected to ground 213.One terminal of the winding I50 of the film-advancing step relay I4! isconnected to ground 213. the other terminal being connected to a secondcontact point "b of the relay lli.

The armature 3|6c of the relay lli is connected to a.souroe of highvoltage through a. resistor 23. and a condenser 23I by-pa-sses the sameto ground.

The contact points llia and 3"?) are so positioneri relative to theimmune 3l5c that when the latter Is attracted by it: met. namesentlydescribed, 3I5c, 3I5b and 3I5a are connected together so that current issupplied to the primary 282 of the induction coil 28I, and via thecontact point 3I6b to the step-relay magnet I50. A second contactor 3I5dis also operable by the armature 3150 of relay 3I5 to close a connectionbetween wires 293 and 295 for a purpose hereinafter described.

A transformer 295 has a primary 295 connected across the branch supplylines 250 and" 254, and a secondary 291 for furnishing current to thefilament of a rectifier tube 298.

The transformer 295 also has a high voltage secondary 295 having itsterminals connected to the plates of the rectifier 238, and a center tapthereof connected to ground at 300.

The transformer 255 further has a heater winding H which is connected tothe heater H of a tube 301. These last-named heater connections are notactually shown, it being customary in electronic circuits to indicatesuch connections in order to make the circuit diagrams less complicated.

The filament wire 302 from secondary 231 is connected via chokes 303 and305 to a wire 305. A filter condenser 306 bridges the choke 303, and acondenser 301 bridges the choke 305, a. third condenser 308 being inseries between the com- 306 and 301 and the chokes 303 and 304.

The photo-electric cell 15, Figure 11 has its cathode 309 connectedthrough a wire 3") to ground 300, Figure 11a, and its anode 3 con--nected via a wire M2 to the control grid 3I3 of the tube 30]. The screengrid 3 of the tube 30I is connected to the wire 305 so that it willreceive thefull voltage of the rectifier. The plate 3I5 of the tube 30Iis connected to one terminal of the magnet coil 3I5. The other terminalof the coil is connected to the wire 305 so that when plate currentflows in the tube 30I, the

- 320 to a secondpotentiometer arm 32I so that the bias on the grid 3I3may be adjusted to any desired value. In adjusting the tube 30I so thatno plate current fiows except when light tending to pass to the cell 15is impeded, both the arm 3I8 and the arm 32I may be adjusted. A biasingresistor 322 is connected from 214 (ahead of the series resistor 210) tothe ground 213. From this it will be seen that when no light or impededlight is received by the cell 15 due to the blocking of apertures 51 and50 by action of the master strip 8| as hereinafter explained, the coil3I5 is energized, thereby closing the contacts 3I5a and 3I0b andactuating the mercury lamp I53. At the same time, due to the closing ofcontacts 3 I So and 3 I 5b,.the magnet I50 is energized, therebyattracting the armature thereof and advancing the pawl I52 on theratchet wheel I. As soon as the control patterns on themaster strip IIin control, uncover the apertures 51 and II.

permitting the cell 10 to receive light, the coil I50 is de-energlzedand the armature spring 320 moves the pawl I52 in the reverse direction,

contact points I25, Figure 12, the other point I26 being connected toground at 326. Thus, whenever either the titleswitch I21 or startingswitch H8 is operated, thereby revolving the ratchet wheel I23, Figure12, the pawl I24 causes engagement of the points I25 and I26 andenergizes the coil II to advance the film I38 a number of stepsdependent on the number of teeth advanced by the ratchet wheel I23.

The purpose of the foregoing arrangement is to assure the advance of thefilm to. cause a spacing between each recording of a particularclassification and the following recording on the same film, as will beclearly set forth presently in the description of the operation of theentire machine. It will be seen that the relay 321, Figure 11, when itsmagnet is energized, is adapted to divert all connections from the flashlamp I63 to the flash lamp 12, and to close a connection via wires 328and 329 across the gap between armature 3I6c and point 3I6a of relay3I6. One side of relay 321 is connected via a wire 330 and wire 381 tothe supply line I08, Figure lie, the other being connected via a wire33I, the title switch I21, Figure 12, and the wires H1 and H3 back tothe supply line 93. Closure of the title switch I21 thus actuates therelay 321, releasing energy from the rectifier through the flash lamp 12which isthereby illuminated.

Referring to'Figure 11, it will be seen that the multiple photo-cell 11has its various cathodes 19 separately connected to suitable electronicamplifiers 332, the common anode 18 having a common connection 333' toall said amplifiers. The amplifiers are of the type adapted to pass acomparatively largeoutputcurrent when their photocell controllingelements are darkened. -As.such amplifiers are well known and theirparticular structures form no part of the present invention, no furtherdescription of them is believed to be required herein.

One output terminal of each amplifier is connected to the conductor.293, which as previously set forth, is adapted to be connected throughthe contactor 8I6d of relay 3I6 and wire 294 with the branch supply line264. Thus it is evident that unless the relay 3I6 is energized, nooutput current can flow from the amplifiers.

The left-hand six amplifiers have their other output terminalsindividually connected to selector magnets 223, 2230., 223b, 2236, 223dand 223e of accumulator orders 20I, 202, 203, 204, 205- and 206respectively as shown in Figure 11, these magnets being connected ontheir other sides to a common conductor 334 leading to the branch supplyline 260. Thus, if relay 3I6 is energized by the darkening of the cell16 and any of the six left-hand cathode members 19 of the multiple cell11 are darkened, the corresponding selector magnets are actuated torelease the latches 225 of their particular accumulator orders.

The seventh amplifier from the left, 332i, is connected via wire 335 tothe magnet of a double throw relay 336 hereinafter referred to as thesubtract relay and having a normally open contact 336a and a normallyclosed contact 33Gb. The contact 33Gb normally maintains a circuit fromthe branch supply line 260 through the as g '7 winding of the clutchshifter magnet I8I shown in detail in Figure 6, thence to the secondbranch conductor :40 is energized all relays m, 242a,

etc., are also energized to throw their armatures to the right. Takingrelay 242c as typical in Figure 11 and the enlarged partial diagram,Figure w 14, it will be seen in Figure 11 that its normally closedcontact point 242Ca is connected to one side of contactor 2280 and it'snormally open contact point 2420b is connected to one side of thecontactor 2290. The other sides of the contactors 2280 and 229c have acommon connection to a wire 3430 which leads to one normally opencontact point 341Da of the double pole carryover relay 341D related tothe accumulator order 205 of next lower denomination. The secondselector magnet 2240 of the accumulator order 204 is also connected onone side to the wire 3430, the other side of 2240 being connected to thewire 366 and thence to one contact 453?) of a normally open relay 450.The second contact 45011 of relay 450 is connected via a wire 366a tothe supply line 260. The moving contact mem-- bers 341Db of carryoverrelay 341D are connected to the conductor 293 and also to one side ofthe carryover contactors 226d. The other side oi carryover contactor226d is adapted when closed to establish a connection directly fromconductor 293 to the magnet 341d, thus bridging the carryover contactor226d. From the connections just described it will be seen that momentaryclosure of the contactor 226d passes current between conductor 293 andconductor 334 through the magnet 341d to energize the same and closecontacts 341Da and 341Dc. The closure of contact 341Dc maintains thecurrent through 3411 even after contactor 226d has opened so that thecarryover relay 341D remains energized. so long as current is maintainedin the conductor 293. It is also evident that closure of contact point,341Da establishes a circuit from conductor 293 through the secondselector magnet 22-30 thence back to conductor 366. The purpose of thisarrangement istoprovide for carryover from accumulator order 205 toaccumulator order 236 as will presently be described in further detailin Further referring'to Figure 11, it will be seen that amplifiers 332g,332h, 3321', 3327' and 332k,

controllable by darkening or blocking respectively of the lightapertures 53 to 53d have output connections via wires. 349, 349a, 349b,3490 and 3494 respectively to the magnetic latches I89, I99, I9I, I92and I93, each of the latter being connected on their other sides to thebrarich supply conductor 280. The magnet of relay 450 is also connectedfrom wire 349d to conductor 260 via its wires 450c and 366a.

It has been set forth in the foregoing description that shutting off ofthe light from the lamp 54 through the apertures of the 51 series causesthe mercury lamp I63 to be illuminated and the -'conduct0r 293 to beenergized; blocking the light series actuatec the magnetic latches ofthe clutch I96. The manner in which these functions are brought aboutand coordinated as follows:

In the foregoing description it has been explained and shown how themaster strip BI is adapted to be drawn between the plates 32 and t,traversing all the above mentioned apertures. The lamin B4 is of suchpower that its rays are able to penetrate the main or blank portion ofthe master strip a d thereby keep the photocells illuminatedso one asonly the blank portion of the strip spans the apertures. Figures 9 and10 illustrate a typical section of strip carrying three item entriesnamely 2.83, 3.61 and 2.54, these entries forming part of a general listcomprising entries under a variety of classifications or accounts, Theseparating and setting down of all items oi a desired group orclassification from among the miscellaneous entries of the general listis accomplished by means of cooperation between the slides 59 andcertain markings or darkened areas on the master strip BI in a mannerfully set forth in the copending application, Serial No. 130,664, andoperable in the present case as follows:

Assuming it is desired to sort out all items of a classification 3613,the slides 3, 6 and B are drawn out as shown in Figure 10, thus bringingtheir apertures 63 in line with the corresponding apertures 51 and 53,Figure 2, and allowing light to pass to the cell 16. The entry 2.83 isof classification 35B, and to represent this classification, blackrectangles 353, 35! and 352 are imprinted or otherwise placed on thestrip 3| opposite the entry and in line with the set apertures in theslides 3, 3 and B when the strip is in the machine.

Asthe record strip is drawn through the machine the rectangles 353, 35Iand 352 simultaneously register under the apertures of slides 3, 6 andB, impeding the light to cell 16. At the same time the entry numerals2.83 themselves are in registry with the window 41, being between themercury lamp I63 and the film I38. The impeding of the light passing tothe cell 16 operates in the manner previously described to cause aninstantaneous illumination of the flash lamp I63. The intense light fromthe lamp I63 penetrates the master strip 3| and photographs the entry2.83 on the film I38 after which the described action of the notchingrelay I39 advances the film into position for the next operation.

The second item entry, namely 7.61 falls in a. classification 35A,having black rectangles 353, 353 and 355 in line with the 3, '5 and Aslides. When these rectangles pass the selecting device set as in Figure9, while the rectangle 353 will block the aperture 63, apertures 63a and60b of the 6 and B slides will remain unblocked, allowing illuminationto pass to the cell 16 and preventing the actuation of the flash-lampI63, so that the item 7.61 is not photographed. Similarly, an item 2.54of a third classification IBB will not be photographed, since theaperture 63 will remain unblocked. Thus in a complete series of Itementries of various classifications recorded on the master strip 3|, onlythose falling in the classification 3613 will darken the photo-cell 13and be recorded or photographed on the film I33. Obviously the slides 59may be set to record any desired one of the possible classifications, sothat by repeated passages of the master strip 3| through the machinewith different settings of the slides 33, item entries of as manydifferent 33 classifications as desired may be separately listed on thehim. Since the mechanism and functions related to the section 35, Figure3, are the same as those of section 34, by setting the slides 356 ofsection 35 for one classificationand slides 59 of section 36 foranother, both classifications The manner in which the device performsadditions, subtractions and the like is as follows:

It has been above noted that the darkening of or the cutting off oflight from the cathodes 19 of multiple cell 11 lying under the apertures53 to 53d, Figure 11, causes actuation of the ma netic latches I39 toI93 respectively of the clutch L95. Referring to Figures 9 and 10, itwill be seen that for each item entry a. series of five small blackrectangles 351, 351a, 351b, 351c and 35101 are arranged in step relationin line with the apertures 53 to 53d. When the classification rectangles350, 35| and 352 darken the cell 16 to actuate the mercury lamp aspreviously described, the closure of relay 3I6, Figure 11a, completes aconnection from branch line 266 through conductors 294, contact 3I6d andconductor 293 to the amplifiers 332, which are thus provided with asource of current as long as the apertures 63, .Bila and 60b remaindarkened. During this period the rectangles 351 to 351d successivelyblock the passage of light through apertures 53 to 53d, causing themagnetic clutch latches I89 to I93 to be successively released. By thismeans, as previously set forth in relation to Figures 6 and 8, theclutch sleeve I12 and gear I16 are revolved through one completerevolution by steps having the angularrelation of 1, 2, 2, 5 and 1.

It has been previously noted that the gear I16,

the release of magnetic latch I93 for the purpose of effectingcarryovers as hereinafter explained. Thus, one complete revolution ofshaft I93 takes place by steps having the angular relation of 1, 2; 2,and 5. So long as the selector detents 225 of the accumulator remainengaged in the notches 22I of the accumulator'orders, no entries canoccur in the latter, the friction drivers I99 merely slipping on thegear wheels 230. If, however, any selector detent 225 is released whilethe shaft I93 performs any of the rotative steps noted, thecorresponding gear 200 and connected accumulator order is rotated byfriction members I99 an angular distance corresponding to the rotativestep. For instance, if detent 225, Figure 7, is released while the shaftI93 is rotated counter-clockwise through its first step of one-tenthrevolution, the accumulator order "I will be turned clockwise from itspresent nine position to the zero position and
